Purpose The purpose of this lab is to design and build a model rocket, examine some of the major concepts in the Physics30 curriculum and to launch the rocket successfully.
Hypothesis We believe that our rocket is strong enough to be launched successfully, the parachute will deploy and the rocket will land without any severe damage.

Procedure and Design
First we cut the cardboard tube to 45 cm to use for our body tube.
We made four fins out of cardboard as well. We made them 15 cm long, one third of the size of the body tube.
We made the nose cone out of Styrofoam and we shaped it into a cone with sand paper. We glued the fins onto the body tube with hot glue.
We made a streamer parachute out of an old Sobey’s plastic bag and tied it to the elastic with some thread. Later we glued the elastic to the inside of the body tube and the nose cone.
We cut out a circle in a piece of wood to use to keep our engine in place and put that in the inside of the rocket.
We painted the rocket a metallic blue and added the JAY BOMB logo on the side.

1st Trial: Our take off was a success Our rocket was controlled Our recovery system did not deploy We were able to retrieve our rocket After the landing our rocket was perfectly intact
2nd Trial: Our take off was a success Our rocket was controlled Our recovery system deploy Our rocket landed on top of an apartment building. We were not able to retrieve it.
Sources of Error
We believe that there was some error in the measurement in our angle of elevation.
Our parachute did not deploy completely in the first trial.
Conclusion
The whole purpose of this lab was to build a rocket and launch it while examining the concepts and ideas that are studied in the physics 30 curriculum. We successfully built a rocket that seemed very sturdy and symmetrical. The thin cardboard tube made a sturdy and light body tube, perfect for reaching a good vertical distance. The dense but light cardboard fins made sturdy fins that were held on perfectly by enough hot glue. Our Styrofoam nose cone was also very lightweight, making our rocket as a whole, very light. Due to this light weight, we achieved a great vertical distance and it took the rocket a long time to coast to the ground, even when the parachute didn’t deploy properly. Unfortunately, when the parachute did deploy properly, we lost it on the roof of an apartment.
